    Advancements in nano-engineering of cement and concrete: a comprehensive review
    (Springer Nature, 2025) Barbhuiya, S.; Das, B.B.; Adak, D.; Katare, V.
    This comprehensive review highlights the transformative potential of nano-engineering in cement and concrete for the construction industry. To provide context, the introduction outlines the motivation and objectives of integrating nano-engineering principles, establishing a foundation for subsequent sections. Building on this, the fundamentals section explores nanotechnology in construction materials, nanoparticle characteristics, and synthesis methods. Transitioning to applications, the focus shifts to nano-engineered cement, examining additive types and their effects on setting time and strength. Further advancing the discussion, nano-engineered concrete composites are analyzed, with emphasis on nanofibre and nanotube reinforcement and their impacts on mechanical and durability properties. Addressing challenges, the review critically examines dispersion issues and durability concerns. Finally, the conclusion synthesizes key findings and discusses implications for the construction industry, offering valuable insights for researchers and professionals in this evolving field. © Qatar University and Springer Nature Switzerland AG 2025.

    Mechanical performance of bio-based materials in structural applications: A comprehensive review
    (Elsevier Ltd, 2025) Barbhuiya, S.; Das, B.B.; Kapoor, K.; Das, A.; Katare, V.
    The pursuit of sustainable materials in construction has led to increased interest in bio-based materials for structural applications. This review paper examines the mechanical performance of structural members made from bio-based materials, including natural fibres, bio-based polymers, and engineered wood products. Key mechanical properties such as tensile, compressive, and flexural strength, as well as durability under environmental stressors, are analyzed to understand their suitability for load-bearing applications. The paper also discusses factors affecting mechanical behaviour, including moisture absorption, temperature sensitivity, and fabrication techniques. A comparative analysis highlights the performance of bio-based materials against conventional materials like steel and concrete, emphasizing both their strengths and limitations. Enhancements in bio-based composites, including hybridization and nanotechnology, are reviewed for their potential to improve mechanical robustness. Additionally, sustainability aspects, such as life cycle assessment and end-of-life biodegradability, are evaluated to underscore the environmental benefits of bio-based structural members. The paper concludes with future research directions, advocating for innovation in bio-based material technology to meet structural demands and support the construction industry's shift toward greener practices. This review aims to provide a foundational understanding for engineers and researchers seeking to integrate bio-based materials into sustainable structural designs. © 2025 The Authors

    Structural performance and implementation challenges of next-generation concrete materials
    (Elsevier Ltd, 2025) Barbhuiya, S.; Das, B.B.; Rajput, A.; Katare, V.; Das, A.K.
    Conventional concrete faces limitations in durability, sustainability, and adaptability to modern structural demands, constraining its use in high-rise, bridge, and extreme-environment applications. This study examines emerging concrete mixes—HPC, UHPC, SCC, FRC, GPC, and 3D-Printed Concrete—by evaluating their mechanical properties, implementation challenges, and future opportunities. A review of experimental data, case studies, and comparative analyses was conducted to assess strength, durability, workability, and structural applications. Results show that HPC and UHPC reach compressive strengths of 60–200 MPa, GPC achieves 40–80 MPa with reduced CO₂ emissions, SCC demonstrates slump flows of 600–800 mm, and fibre reinforcement enhances tensile strength to 8–15 MPa. These findings highlight superior performance, sustainability, and constructability, though high costs, lack of standards, and scalability issues remain obstacles to widespread adoption. This review uniquely integrates comparative insights on High-Performance, Ultra-High-Performance, Self-Compacting, Fibre-Reinforced, Geopolymer, and 3D-Printed concretes, bridging laboratory findings with real-world applications. Unlike existing reviews, it emphasizes structural implementation challenges and opportunities. Key obstacles—including high cost, lack of standards, and scalability—are outlined to contextualize pathways for sustainable adoption. Overall, next-generation concretes deliver enhanced strength, durability, and sustainability, making them viable for critical infrastructure. Future studies should focus on advancing standardization, integrating nanotechnology and AI for mix optimization, and developing cost-effective, large-scale deployment strategies. © 2025 The Authors
